There is some slight pilling, but I think you can wear it comfortably without any tightness under the arms. The neckline is shallow, and it's thin, soft, and lightweight, making it comfortable to wear. It's a long, elegant knit-like, stretchy, lightweight, and comfortable dress. ^ ^ Approx. 45cm under the armpits, approx. 91cm from the shoulder, approx. 93cm from the top of the shoulder. #DinnerParty #HotelLunch #Greetings #Date #Transportation #LunchParty #Dinner #Holiday #SchoolEvents #InformationSession #René #Rene #FOXEY #Foxey #M'sGracy #TOCCA Size...M
